REGULATOR Fon GAsLJE'r's.'

To all whom it may concern.' Y

Be it known that I, CHARLES city of St. Louis, Statev of Missouri, have' invented a certain new and useful Im rovement in Regulators for Gas-Jets, of which the My inventionl relates to burners and where itis necessary to introd uce a. jet of gas for mixture with air, the size of which can be regulated at will.

My .present invention is an improvement upon that patented by me on beptember .18th, 190e, No. 831,512.-

Of the various devices which have heretofore been employed all either depend on artificial pressure or cut-the jet into numerous sub-jets, all of which fail to accomplish the best results.

My devicejfurnishes a 'solid cylindrical stream of gas mixed with air, the size .of

which may be regulated as desired and from which the maximum results both as to coi-n-l bustion and efliciency can beobtained, yet lwhile the said jet is introducedv in'a cylindricalform into the exact center of the bunsen` Referring to the accompanying drawings which form a part of the specification, Figure 1 shows a'vertical section of my entire device, and Fig. 2 shows a vertical section of the jet proper and the means for-regulating the size thereof, said drawing being somewhat enlarged.

shade 2 and'crown 18.

20 and 21 show pivots about which the c'ap and cylinder revolve; the object of constructying these parts so that they revolve about this axis being that newfmantles frequently smoke' or otherwise burn ythe parts; and this enables the device to be swung out of the way until a new mantle. is fully broken in.

-22 is an ordinary mantel such as is usually supplied to this kindof a lamp.

23' is Ithe burner tube the upper end of which is contracted and slit part of the way of-its length in a-mannerhsimilarto that describedin my former patentabove-referred to. The slitsr aref so Wide lthat when theupper portion is contracted to the minimum and closed either entirely or approximately they still furnish enough open space to allow gas mixed with'air to pass there through, so that immediately upon opening the same by 'uselof the pinion 1() there is a supply of gas ready to escapefor i nition purposes. The pinion 10 on the regu ator cap meshing with the bevel gear 9 operating by the button 11 furnis-hes a simple and ready means for raising or lowering this ca 'thereby allowing the gas to either escape or e shut off through the t'ube 23. In my former atent, above referred to, these slits in tu e 23 were some- What Widerjmid'way their length, but I lnd that enough surplus space is provided by a parallel opening, the object being to have the escape paths for gas always larger than the orifice through which it asses for ignition.

In my former device' t ie turning or regulating ofthe cap 10 was difficult, especially when the parts became heated, which difficulty is removed by the pinion and bevel gear above described'. A. further practical feature is found in my means of swinging the cylinder and its ca outof vthe way when new mantles are being rst used.

What I claim as new and desire to secure by Letters Patent of the United States is:

A gas burner consisting in the combination of a burner tube'providcd with a number of slits for the escape of gas extending downwel-diy from its upper end, thereby forming flexible portions which may be bent together et their free ends to Vary the size of the slits between them, said tube having also a screwthreacled. portion below seid slits, a Buns'en tube provided with an epertured, flaring bottom midv mounted upon. said burner tube below said. serew-threaded portion, a regula,- toi oep having en opening)r in the center of its summit coincident with the exis of seid tubes and a screw-threaded section to engage the 'threads upon said. burner tube, vgeen, teeth upon the exterior of said cap, a bevel gear meshing with said teeth and carried by a.

stem journaled on said ,burner tube and having on its outer end a button by which, it may be turned, for the purpose set forth.
